I believe the answer is:
categorical
I believe this clue is a double definition.
'unqualified' is the first definition.
(similar in meaning)
'unconditional' is the second definition.

(Other definitions for categorical that I've seen before include "unqualified" , "that's very clear" , "Unambiguously explicit" , "Unconditional" .)
